Questions about NASA discovery of 54 “habitable” planets
For Star Trek fans, the idea of finding dozens of planets capable of supporting advanced life forms is a thrilling possibility.

NASA’s Kepler mission recently discovered its first Earth-size planet candidates and its first candidates in the “habitable zone,” a region where liquid water could exist on a planet’s surface.
“The fact that we’ve found so many planet candidates in such a tiny fraction of the sky suggests there are countless planets orbiting sun-like stars in our galaxy,” said William Borucki of NASA’s Ames Research Center. “We went from zero to 68 Earth-sized planet candidates and zero to 54 candidates in the habitable zone, some of which could have moons with liquid water.”
The fact that these planets may contain water raises the prospect they could contain bacterial life – or even more advanced life forms. But one Christian astrophysicist is skeptical of reading too much into NASA’s announcement.
“Habitable zone is a bit of an overstatement,” says Hugh Ross Ph.D., the founder of Reasons to Believe. Dr. Ross explains that planets have previously been discovered that contain water – too much water. “They have 500 to 1,000 times as much water as Earth,” he notes. “When you have that much water, you don’t get continents above sea level.”
